SPECIFICATION forming part of Letters Patent No. 792,957, dated June 20,1905.

Application filed February 4, 1905. serial No. 244,205.

To all whom it may concern:

Be it known that we, JOSEPH APPLEBY and EDWIN APPLEBY,subjeets of theKing of Great Britain, residing at 4:5 Tower road, Aston, in the countyof Warwick, England, have invented new and useful Improvements Relatingto Cotton Spinning and Like Machinery, of which the following is aspecification.

This invention relates to machinery for cotton spinning and twisting andfor like purposes, and has for its object to provide for the more readyand eifective adjustment and setting or fixing of the thread-guides orguides and snarl-catchers employed with such machinery.

Our invention comprises the combination, with metallic thread-boardflaps or holders for the guides or guides and snarl-catchers, ofself-locking or snap-fastening devices, permitting of very ready andaccurate adjustment and setting of the said guides and snarl-catchers;also, an improved construction of such holders and the arrangement ofthe same in independent attachment with the thread-board rail or otherpart of the machine with which they are to be employed.

Referring to the two accompanying sheets of explanatory drawings, Figurel is an illustration of a steel or other metal blank for the formationof one type of the front or movable hinged portion of one of ourthreadboard flaps or supports or holders for the thread'guides or guidesand snarl-catchers. Fig. 2 is a plan, Fig. 3 a side View, and Fig. 1 aninverted plan, of the said blank when pressed or formed to the requiredshape or configuration. Fig. 5 is an illustration of a steel or othermetal blank for the formation of one type of the back or fixed hingedportion of one of our thread-board flaps. Fig. 6 is a plan, Fig. 7 aninverted plan, and Fig. 8 an end view, of the said blank when pressed orformed to the required shape or configuration. Fig. 9 is an illustrationof a steel or other metal blank for the formation of'one type oflever-grip or snap-fastening for our thread-board flaps. Fig. 10 is aplan, and Fig. 11 a side view, of the lever grip or snap formed from thesaid blank. Fig. 12 is an illustration of a steel or other metal blankfor the formation of one type of friction or grip plate for use with ourthread-board. Fig. 13 is a plan, and Fig. 1A a front view, of thefriction or grip plate formed from the said blank. Fig. 15 is a plan,and Fig. 16 a side view, of our complete thread board flap with combinedguide and snarl-catcher in position for service and secured upon a metalstrip for attachment to the rail or like part of the machine. Fig. 17 isa view showing the front hinged portion of the flap or support or holderwith the guide and snarl-catcher secured thereto thrown back to itsout-of-service position. Fig. 18 is a plan, and Fig. 19 aside view, ofwhat is known as a pot-eye type of guide as adapted for use whenrequired with our threadboard flaps or supports or holders in place of acombined guide and snarl-catcher,as aforesaid. Fig. 20 is a side view,and Fig. 21 a plan, of a support or holder with the front and backportions formed from the one piece or blank of metal and fitted with ourself-locking or snap-fastening device for holding a thread.- guidewithout snarl-catcher. Fig. 22 is a side view of a simplified form ofour hinged thread-board flap, in which the lever, grip, or snap actsdirectly upon the shank of the guide and snarl-catcher, or without theintervention of either a spring piece or a friction or grip plate. Fig.23 is a plan showing the hinging of the front and back portions of thethreadboard flap and the provision of abutmentstops on the joint. Fig.24 is a plan of the front portion alone. Fig. 25 is a plan of asheet-steel spring which is sometimes employed instead of the grip-plateshown by Figs. 12 to 1 k.

- The same reference-letters in the different views indicate the same orsimilar parts.

In the application of our invention as in the example shown by Figs. 1to 17 inclusive, we make each thread-board flap or hinged supportor'holder for a thread-guide and.

finished shape or configuration indicated. The bent-up ears or lugs 0serve as bearings or supports for a rivet or pin 03, on which is mountedthe lever-like grip-piece or snap a for securing the combinedguide andsnarlcatcher a in any position within its range of adjustment. The backportion f of each thread-board flap or guide holder, made from a blanksuch as is shown at Fig. 5, has the aforesaid front portion hingedthereto, as is clearly indicated at Figs. 15, 16, and 17. For theattachment of the desired number of thread-board flaps to thethread-board rail or like part of the cotton-spinning or similar machinewe sometimes employ a metal strip, such as g, and secure the backportions, such as f, of the thread-board flaps to the said strip bymeans of ears or lugs, as It, projecting from the back portion f, andwhich engage or are riveted or fitted tightly within corresponding holesor apertures in the strip. The strip g, having the thread-board flapsfixed thereto, as aforesaid, is secured to the rail or like part of themachine by screws inserted through apertures, as 2'. The projections orthe like may be formed upon the strip and the corresponding holes orapertures within the thread-board back plates or portions f. With astrip, as 9, we greatly facilitate the secure fixing of the respectivethread-board flaps or guide-holders in position to the required gage tosuit any frame or machine while providing for the ready detachment ofany one of them. When the grip-lever or snap e is I in the positionshown by dotted lines at Fig. 16, the guide and snarl-catcher a can bepushed in or drawn out to any position within the limits fixed by thelength of its shank or stem part, or it may be entirely withdrawn, ifdesired; but when the grip-lever is pulled or pressed up to thefull-line position in the said figure the guide a is securely held inthe desired position.

To permit of the adjustment of the guide or the combined guide andsnarl-catcher in both longitudinal and transverse directions, weinterpose between the lever grip or snap e and the inner surface of thefront portionb of the holder a friction or'grip plate, as j, which onthe release of the snap by depressing it to the dotted-line position(shown at Fig. 16) is free to slide between the ears or bearing-pieces 0upon the lever pivot-pin 61. The said friction or grip plate j issuitably shaped, as shown at Figs. 13 and 1 1, for engaging thepivot-pin d and to embrace the shank of the guide a. A flat seating,such as is, is also provided to receive the thrust or pressure imposedby the cam-like projection Z of the lever grip 0r snap 6 when the latteris closed. The friction or grip plate j, shaped as described and asillustrated, can be readily made to slide between the ears 0 of the partb after the release of the lever-grip e for accu rate lateraladjustment; but any twisting or circular movement, such as would throwthe guide out of adjustment, is effectually prevented. Longitudinaladjustment is obtained by drawing out or pushing in the guide, asaforesaid.

The front hinged portion Z) of the threadboard flap or guide-holder canbe prevented in various ways from dropping when in its service positionbelow a right angle with the back portion f. In the example shown by theFigs. 1 to 17 such result is attained by the formation of an abutment mon the back plate or portion f. The grip-lever 6 can also be readilymade to serve the same purpose and in addition to serve as a stiffeneror strut for the front portion Z). I

Each thread-board flap or guide-holder has its own independenthinge-joint pin and is thus complete in itself and may be removed andreplaced without disturbance of any of the others employed with it.

In the example shown at Figs. 20 and 21 our gripping or snap devices,including the lever e and a friction-plate j, as aforesaid, are fittedupon a holder made from a single plate instead of from a pair of hingedplates or parts as aforesaid.

Instead of employing a friction-plate, such as we sometimes interpose asheet-steel spring, such as shown at Fig. 25, between the lever-grip eand the inner surface of the front part bof the holder. We sometimesalso dispense with both of such elements (the frictionplate and thespring) and cause the lever grip or snap to act directly upon the shankof the guide a, as in the example illustrated by Figs. 22-, 23, and 24.The said figures also illustrate the employment of abutting portions,such as it, in the hinge-joint to prevent the front plate or part I)from dropping when in service below a right angle with the back plate orpart f.

The shanks of the guides or combined guides and snarl-catchers a, alsoof the pot-eye type of guides, as illustrated at Figs. 18 and 19, may beof a D shape or provided with a flat and serrated surface for abuttingupon the inner surface of the front part Z) of the holder. Whendispensing with the use of a friction plate, as f, or a spring, such asshown at Fig. 25, between the lever-grip e and the under surface of thefront part b of the holder, we preferably provide a semicircularseating, as 0, in the front part I) and indent or serrate the same toprovide an effectual grippingsurface. In this case the rounded orcircular portion of the guide-shank fits within or upon the seating,while the fiat portion is next the lever-grip. The shank is preferablythreaded along its circular portion to correspond with the aforesaidindents orserrations of the seatmg.

In thread-board flaps or guide-holders of the type shown by Figs. 22 to24 lateral or transverse adjustment is arranged for by making thescrew-holes, as p, for the direct attachment of the flap to the rail orlike part of the machine of an elongated form, as illus trated. With thescrews slackened transverse adjustment may then be readily effected.With this thread-board flap the aforesaid metal strip 9 is not employed.The same method of attachment and means for obtaining transverseadjustment may be used with the thread-board flaps, such as illustratedin thelother figures, the strip g being dispensed Wit 1.

The pot-eye type of guides a (illustrated at Figs. 18 and 19) are madefrom flat steel strips pressed or formed to the shape shown and withspring-like jaws at one end for gripping the pot or porcelain eye q.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
